PACKING-NORMING APPARATUS. n

Application led October 2, 1922i. Serial No. 591,936.

. My inventionbelongs to ythat general' class of devices known as packing forming appa-- ratus, and moreparticularly toY a mechanism or apparatus particularly adapted to be placed between a supply of material which may be initially or partially formed or not,

as the case may be, and between a braiding getherand maintained in relation to each other so as to provide a unitary structure.

It is particularly designed to be used in the manufacture of what may be termed flexible metallic packing, and preferably that vtype of metallic packing which is provid-ed with a rubber, elastic, resilient or other backing, insert or core. The invention has among its objects the production of an apparatus of the kind described that is simple, convenient, durable, compact, efficient, reliable and satisfactory for use Wherever found applicable. More particularly it vhas as an object the production of al guide or die Which Will lay the parts together in a predetermined relationship and also accurately gauge or reshape o'r resize the metallic body or other parte, depending` on the type of packing .so that a uniform product is produced. Many other objects and advantages of the conf struction hereinA shown and describedv will'` be obvious to those skilled in the artfrom 'the' disclosure herein given.

To this end 'myinventi'on consists in the nov-el construction, arrangement and combination :of parts herein shownand described, 'and more particularly pointed.y `out in the claims. f

`In the diawings', wherein like reference characters indicate like or corresponding parts, Y. 'l

Figjis a top plan Vview'of the same; Fig. 3 is a s-ectionalviewtaken substantially on Yline 3-3 of Fig. 2;

.tyre y i Fig. 4 is a. sec-tional `View taken substantiallyon line if-Ll of Fig. 3; f Fig. 5 is a perspective View illustrating the type of packing which may be made up or formed by the particular type of die shown; n v v Fig. 6 is a sec-tional view takenA on line 66 of Fig. 7, illustrating L1-.modified construction; I j Fig. 7 is a sectional ,view` taken substantially on line 'Tf-7 of Fig. 6; i p Fig. S. is a bottom view of lthe member 31 .shown in Fig. 7 and 'i Fig. 9 is a sectionalview taken substantially on line 9-9 of Fig. 6.

Referring to the draWin-gsun Which the preferred embodiment of the device is shown, it may be mentioned that this particular die is adapted to form up and asf semble the 'elements inpacking similarl to that shown in Fig. 5, this` particular type of packing being merely illustrative of `nu-y merous arrangements, kinds, vand styles of elements which may be assembled together to produce the packing. In vthe packing illustrated l represents a suitable body, for instance a metallic body or facing, for example, made up of soft or other metaljsheets, strips or ribbons,-or Wire, shreds or the like, and 2 and 3 a backing insert or coremade up of rubber, asbestos or any suitable equivalent mate-rial Which is preferably yielding, elastic or resilient, the several parts being assembled and maintained together by means of abraided lcover 4, or any equivalent securing means. In describing lthe packing, I do not Wish to be understood as in any Way limiting the useof the apparatus to Amaking 'a packing similar to that shown in Fig. 5, asthe packing itself forms nopart of the present invent-ion, and the apparatus shown and constituting -my` invention may be modi-lied or varied in details depending upon the particulartype of packing to Vbe nafde,A their sizes, shapes -andmaterials emf ployed.- This packing is illustrated because the type of die or rformingr appara-tus shown has been designed to produce this particular bolts 10 orthecuuivalents. The purpose of inakingthe saine in a plurality ot' parts is ior convenience in using' and constructing the die, and consequently l do not Wish to be understood as intiinating that the details of construction in this connection are limited to the particular construction shown, as various die makers may have various ideas as tothe 1most desirableivay to construct the saine. rihe die is provided Withf an opening or throat 5, as mentioned, the discharge end of which substantially corresl'ionds Y'for a portion of its distance with the throat or discharge end 11., and corresponding Ain `contour to the product tobe discharged there `from Whilethe throat at the inlet is pret eably iiared, that is, it taperslo f'ardthe discharge end, as indicated at 1i.` The wall should be substantially smooth, and'in `ilact as the material is passed;.therethrough it takes on a polish, so that the inateri al passing therethrough generally does'so with very little friction `even though it may becoin# pacted or compressed, sometimes toa considerable extent. The guide-Ways or pas-v sages 6 in the particular device shown correspond in contour and size With `the Yelements 2 and 3, these being in the nature ot grooves, as indicated at 13 in the `parts 8 and S) shown, plates 14 being provided. lor maintaining the eleiiients in the grooves. These plates may be secured in place by screws 15"or the equivalent. Obviously, the plates 'lt may be integral with the parts 8 and Q i desired, this, as betere mentioned,

being immaterial. l

^ l have shown the device provided with an adjustable member 1li arranged .in `the passage 5, and which maybe adjusted to gauge, resize, reiorm or vary the sizes ot the packing discharged so that a uni'lori'n product may be produced, or' the product slightly varied. by` making the part 1 larger or smaller, as the :asc may be; As shown, partY 1G in'ovidcd with the part 1,7 arrangedv tocooperate with an adjusting inemherll. The die, as shown, is mounted in supports 19 and 2l), which may he as desired. I have illustrated how` the par-i319 may be slotted, as indicated at and forinedto engage the liange'on the screw 1S, which sci'eiv provided with :if thumb or Wing nut end 2d. Ubrioiisly, turning the screw 1S Will control the position et' the` part 16. Generally VI prefer to provide a slight clearance at the endmofl, as indicated at 22, The material passing through the die will prevent inward yopening movement of the member 16, While the screw will maintain it against spreading. By adjusting the piece 16 or by replacing it by pieces of different sizes or shapes, the product discharged may be' :varied at will.

In the manufacture olf the packing of the type shown in Fig. 5, the body l ted up through the openings 3, and parts 2 and 3 through the openings and l", it being immaterial as to just hoiv the 'feeding is done through the part, but ordinarily the packing is pulledV through, the parts 2 and 3 beinglaid in place or assembled in the desired relation with the body l.` After being so assembled, the parts are secured together `in any suitable nianner, not necessary to describe herein, Vthe braiding 4l being merely illustrative of `one method ot' lining `them and maintaining them in the desired relation as a unitary structure. `In making the die, one advantage of making the same in two parts 8 and 9, divided soas to pei'- i'nit the separation ot the saine and open ing of the space 5, is that atter the machine has been in operation and there is Vpacking passing throngln'it is a` V\coiiiparatively. easy matter to slip off one guide, former or die and insert ai new one so as to vary thesize or shape, or the arrangement ofthe parts without severing the packing elements par-` ticularly the body 1 making it possible to` operate and make continuous lengths of packing, varying the 'sizev from time to time, or arrangement ot the parts, Without stopping the inacl'iine except forthe change ot the die( Oli course, the parts 2 and 3 may be inodiiiedin size and shape and the body 1 may have more or less material ted to the die, as the clase may lie/but in the main i there is a continuous and unbroken strip ol packing. This saves some loss oit time, as the change may be made :in this manner much quickerthan Where the stripis sev` cred and restarted through the machine, covering machine, ctc; As betere Istated, 1

dornot wish to liiiiit myself ,toy the particu j llar detailsol: Vconstruction illustrated, as the diilerent dies may 4vary Vsoine,.dependV ing upon the type of packing to be n'iade.

I have/illustrated a modified construction 'of' tornnng apparatus in Figst' to '9, inY which V3l represents a V,die having an open ing 33 'therethrough corresponding with the 5 in the other die,132 being anadj-ustable member for v controlling` the l forming ofthebody. VI have shown in this instance a die suitable 'for making packingV similar toV that previously describedr In this case the entrance side of the opening is flared, as indicated `at 34, the parts being secured together andthe adjustment controlledgby means ot the bolts 35. or their equivalents. This partieularpart shapes the body, While acooperatingpart is arranged in proximity thereto for applyngrthe cooperating parts 2 and `3 tothe body l. As shown, there is' provided plates 36 and 36 which are formed with Wings 37 and 39 respectively, and 38 and 40, the same being adapted to form an opening corresponding 'in size to the finished packing product. The two parts are maintained in operative relation by means of plates 41 and the bolts 42,101' equivalent means for the purpose. In this case the body l ispassed throughtlie shaping and sizing die 31 and thence as it passes through the assembling die mentioned, the several parts of the packing are assembled together separately to be fixed or secured together in any suitable manner.

' In the claims wherein I refer to a packing consisting of a plurality of elements or parts which are to be assembled or laid togetherin a desired manner to produce a finished product, I Wish to be understood as not limiting myself to the specilic sizes, shapes, arrangements or materials referred to in the preceding description, nor do I wish to limit the use of the forming die or apparatus to use in connection with any particular type of apparatus for initially forming the packing prior to its being guided or controlled by the die, nor with any particular mechanism for covering, fixing, joining, wrapping, braiding or otherwise securing the parts together, the present apparatus being designed to receive the materials whether initially formed or not and to assemble them or arrange them together in a desired manner, whereby they may be maintained in the desired relation in any preferred manner or by any suitable fixing means. rI`he particular apparatus shown and described may be adapted and used for forming, shaping, sizing and assembling the parts, or for any one or more of these purposes, either any single operation referred to or such ones combined as may be desired.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence I do not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination ofparts herein shown and described, or uses mentioned.

What I claim as new and-desire to secure by Letters Patent is:
